Primus and Fishbone share bill at Gratwick Park in Tonawanda

Primus kicked off 2014 with an epic New Year’s Eve party in Oakland, Calif., dubbed “Primus and the Chocolate Factory,” during which Les Claypool, Larry LaLonde and Tim Alexander performed the entirety of the original “Wille Wonka”-themed film soundtrack, as folks decked out in Oompa Loompa costumes cavorted about the stage.

How do you top that? Well, for the ever strange and consistently awesome alt-funk-metal-jam ensemble, topping itself hasn’t proven to be much of a problem. They just keep getting weirder.

Primus will reprise the “Willie Wonka” theme show later in the year, but for the band’s summer tour expect a career-spanning set of psychedelic, hypnagogic hyper-funk masterpieces. The tour stops at Gratwick Park in North Tonawanda for an early show – starting at 4 p.m. Sunday – as part of the Niagara River Rocks series.

As if Primus wasn’t enough, Sunday’s show also will feature a set from legendary Los Angeles alt-funk/punk/ska/rock outfit Fishbone. In the midst of its 25th anniversary tour, the band – still boasting founding members Angelo Moore, Norwood Fisher and Dirty Walt – is touring in support of its latest effort, “Intrinsically Intertwined.”
